What is screen tearing?
Screen tearing is a distortion on the screen that occurs when the graphics processor is out of sync with the display. It causes a horizontal line to appear on the screen while playing a video or a video game. This happens when the top part of the video is not in sync with the bottom. When the graphics processing unit is under heavy load it can mess up the video refresh rate where one part of the frame is drawn in one part of the screen and the others are redrawn into another part of the screen, making a vertical line appear on the screen.
How to fix screen tearing?
-Lower the resolution so that the graphics processing unit does not get overloaded.
-You can upgrade to a more powerful video card to support the videos and video games you play on your computer.
-In your google chrome, you can enable Hardware Acceleration this allows you to improve video playback within the web browser.
